Menendez, D-N.J., teamed up with a fellow Cuban-American senator. Marco Rubio of Florida, and introduced a resolution calling for the immediate extradition of Chesimard and other fugitives now living in Cuba.

"As we seek a more responsible U.S.-Cuba policy, we must make it clear that Cuba must end the shameful practice of harboring to American fugitives who have committed egregious acts, including murdering American police officers, hijacking planes, or trafficking arms,” said Menendez, the top Democrat on the Senate Foreign Relations Committee.

The Fraternal Order of Police endorsed the resolution in a letter to Menendez and Rubio, saying “the blood of American law enforcement officers shed while doing their job in American soil demands justice and the deliberate protection of these killers should not be tolerated within the community of nations.”

New Jersey lawmakers of both parties have seethed over Cuba’s refusal to extradite Chesimard, even as President Barack Obama moved toward normalizing relations with the communist country. President Donald Trump singled her out in June 2017 when he rolled back Obama’s policies.

Chesimard, who is on FBI’s list of the most wanted terrorists, has lived in Cuba since 1984 after escaping from prison. The Black Liberation Army member had been sentenced to life imprisonment after being convicted in the killing of state Police Trooper Werner Foerster in a shootout on the New Jersey Turnpike in 1973.

The FBI and the Office of the New Jersey State Attorney General have offered a combined $2 million for information leading to her arrest.

Menendez said Cuba is believed to house more than 70 fugitives who committed crimes in the United States.
